In this article, I’ll share my personal journey with this root veggie, walk you through the ultimate Hawaiian purple sweet potato recipe step-by-step, explain its health benefits, and answer those lingering questions you didn’t even know you had. Plus, I’ll show you how this show-stopping ingredient can shine in anything from pies to soups.
The Unexpected Journey of Flavor and Color
From Backyard Greens to Hawaiian Violets
Growing up in a Northern California town, Sunday meals were both tradition and ritual. We didn’t call it “plant-based” back then—we just ate from the backyard. We weren’t trying to be trendy; we just couldn’t imagine food that didn’t come from soil coaxes by love. Now fast forward 20 years, standing in my Portland kitchen unlocking the earthy magic of purple sweet potatoes, it feels like coming full circle.
The first time I discovered the vibrant Hawaiian variety, I had no idea how it would change both my cooking and the way I approached comfort food. The Hawaiian purple sweet potato recipe I developed since then doesn’t just taste incredible—it bursts with heritage, nourishment, and creative potential. I’ve featured them in multiple creations on my blog, like purple potato pie bars and baked purple sweet potato recipes.
Why Hawaiian Purple Sweet Potatoes?
Known locally as “Okinawan sweet potatoes,” they were brought to Hawaii centuries ago from Polynesia and have become embedded in the local diet. Rich in antioxidants and a stunning bright violet hue, the Hawaiian purple sweet potato recipe has quickly become a go-to dish in my weekly cooking. Whenever I need a base for something comforting, warming, and stunning enough to post on Instagram—this is it.
Not to be confused with ube (more on that later), these potatoes are dense, slightly sweet, and ideal for roasting, mashing, or turning into purple sweet potato pie—and everything in-between.
Whether it’s a chilly January night or a summer potluck, this root gets people talking. Plus, nutritional value? Through the roof. Purple foods are a clear sign of phytonutrient power, especially anthocyanins which support brain and heart health.

The Why Behind the Color and Flavor
Nutritional Power of Purple
These roots aren’t just beautiful—they’re incredibly good for you. Hawaiian purple sweet potatoes are loaded with anthocyanins, a type of antioxidant that gives blueberries and acai their claim to fame. According to PMC, foods richer in anthocyanins can help reduce the risk of heart disease and support cognitive function as we age.
Compared to orange sweet potatoes, the purple kind often delivers more potassium and similar levels of fiber. This makes our Hawaiian purple sweet potato recipe not just tasty, but deeply nourishing.
Their natural sugars are minimal, yet they roast to a caramelized softness without needing added sweeteners.
Purple Sweet Potato vs. Ube: Know the Difference
It’s easy to confuse Hawaiian purple sweet potatoes with ube. But here’s what makes them different:
| Hawaiian Purple Sweet Potato | Ube |
|---|---|
| Firm, earthy, mild sweet flavor | Softer, more floral and vanilla flavor |
| Used in savory & sweet dishes | Mostly featured in desserts |
| Available in Hawaii and U.S. markets | Mostly imported and found in Asian markets |
Need examples? My purple potato soup highlights the earthy profile of Hawaiian sweet potatoes, without clashing with savory flavors, unlike ube.
